Aemulor would be a bit on the slow side on a RiscPC, wouldn't it? IMO the more important aspect is that it's showing a more flexible version of RO than we've had before, which could conceivably end up closing the fork, especially if RO6 features start getting ported (RO6 is definitely nicer to use than 5, I've not tried the latest ROOL release yet).

The problem with throwing away the decrepit old stuff is that you've then got a shiny new OS but no software for it, which makes getting people to use it almost as hard as it is to get them using the decrepit old mess.
